Filed: 1976-12-13
Abstract: 1505632 Vacuum cleaners ELECTROLUX Ltd 13 Dec 1976 51929/76 Heading A4F  [Also in Division H1] A vacuum cleaner comprising a motor/fan unit (not shown) having an on/off switch 25 actuable by a member 27, is provided with a servomotor  10 which is effective to position a rocker arm 21 to maintain the switch 25 closed only if a dust bag is in position in the cleaner. As shown depression of member 27 causes a finger 29 to bear on a portion 21a of the arm and pivot the arm anticlockwise so that the portion 21a closes the switch so starting the fan. The resulting negative pressure caused by the dust bag (for example arranged as disclosed in Specification 1494310) is applied to chamber 15 and causes the diaphragm 14 to move to the left and so move the rocker arm 21, whose pivot 22 is mounted in grooves 23, to the left so that even when the member 27 is released the portion 21a holds the switch closed. Subsequent depression of member 27 causes the finger 29 to bear on the portion 21 b and so pivot the arm 21 clockwise to open the switch, the arm returning to its original position under the action of a spring 30. If there is no dust bag in the cleaner, the diaphragm 14 and hence the arm 21 do not move to the left so that on release of the member 27 the switch is opened.

Title: Device for effecting the manual engagement of a mechanical clutch
IPC: H04L13/04
Filed: 1967-12-07
Abstract: 1,148,230. Clutch control. CREED & CO. Ltd. 7 Dec., 1967 [13 Dec., 1966], No. 55746/67. Heading F2L. A clutch control mechanism is optionally operable to engage the clutch for as long as desired or for a whole revolution (or a part revolution). The clutch may be employed in a magnetic tape drive and is controlled by two keys 1, 2 which pivot about a shaft 3. Key 1 has an arm 1b on which a pawl 7 is pivoted which normally engages beneath an arm of a clutch control pawl 10 which is biased by a spring 12 to engage a stop 13a of a clutch wheel 13 to disengage the clutch. On depression of the key 1 to a position in which it is retained by a latch 14, the pawl 7 is raised and pivots the pawl 10 anticlockwise to release the stop 13a and permit the clutch to engage. To release the clutch the key 2 is depressed and a projection of the key releases the latch 14 from the key 1 which is then returned to its inoperative position by a spring 6, and the pawl 10 is biased by its spring to engage the clutch wheel 13 and disengage the clutch when the stop 13a is engaged. To engage the clutch for one revolution (or a part revolution, according to the design of the arrangement), the key 2 is depressed. During the initial part of the movement, a pin 5 on the key 2 engages a projection 1a on the key 1 which is thereby depressed to release the pawl 10 from the stop 13a to engage the clutch. Further movement of the key 2 causes an arm 2b thereof to engage and pivot clockwise a member 15 which in turn pivots the pawl 7 anticlockwise to release the pawl 10 so that the clutch is disengaged after one revolution of the clutch wheel 13. In a modification the member 15 is omitted, the arm 2b engaging directly with pawl 7.

Filed: 1968-11-28
Abstract: 1,247,365. Nitrophosphate fertilizers. ESSO RESEARCH & ENG. CO. 28 Nov., 1968 [30 Nov., 1967; 23 Aug., 1968], No. 56577/68. Heading C1A. A continuous process for the production of nitrophosphate fertilizers of varying N/P 2 O 5  ratios comprises acidulating a calcium containing phosphorous source in the presence of "NH 4 HS0 4 ", removing the precipitated CaSO 4 , converting the CaSO 4  to CaCO 3  and (NH 4 ) 2 SO 4  and removing the CaCO 3  precipitate, converting the (NH 4 ) 2 SO 4  to  "NH 4 HSO 4 " and recycling the latter to the acidulation step. After the removal of CaSO 4 , NH3 and agricultural nutrients such as KCl, KNO 3 , K 2 SO 4 , ammonium polyphosphates or mixtures thereof, and traces of Zn, B, Mn, Cu, Fe and Mo or other known nutrients, may be added to the calcium-free liquor. The CaSO 4  may be removed by filtering. The CaSO 4  may be converted to CaCO 3  and (NH 4 ) 2 SO 4  by reaction with NH 3  and CO 2 , (NH 4 ) 2 CO 3  or ammonium carbamate. The (NH 4 ) 2 SO 4  may be converted to "NH 4 HSO 4 " by heating (the NH 3  produced may be recycled) for example by adding to molten NH 4 HSO 4  or alternatively by the addition of H 2 SO 4 , use of ion exchange resins, or electrolytic convertion. By "NH 4 - HSO 4 " is meant true NH 4 HSO 4  or (NH 4 ) 2 S 2 O 7  or mixtures thereof and (NH 4 ) 2 SO 4  may also be present. The "NH 4 HSO 4 " may be added to the phosphorus source either prior to, during or after the addition of the acid. The phosphorus source may be phosphate rock. The acid used for the acidulation is preferably nitric acid which may also contain H 3 PO 4  and/or H 2 SO 4 . The heat required for the CaSO 4  conversion or the (NH 4 ) 2 SO 4  decomposition may be supplied by heat exchange with molten "NH 4 HSO 4 ". An external source of CaSO 4  may be added to the reaction sequence whereupon a (NH 4 ) 2 SO 4  by-product may be removed. The resultant nitrophosphosphate fertilizer product may be recovered by prilling a concentrated melt, granulating a concentrated melt, or evaporating a solution thereof in a heated granulator. In a comparative example the NH 4 HSO 4  may be replaced by (NH 4 ) 2 SO 4  and the recycling may be dispensed with.
